FLAME FAILURE FUNCTIONAL CHECK

PILOT WILL NOT STAY LIT OR FIRE GOES OUT

If the appliance goes out in use continually, this may mean

that the

oxygen depletion sensor has been activated. The appliance

should not be used

until the cause has been found and rectified.

Ensure there is no debris around the pilot assembly, e.g.

coal, soot, etc.

Check for fluff in the pilot aeration hole. See Diagram 7.

Light the pilot and keep the control knob pushed in at least

10 seconds before letting go

2. fault finding

This is for use only by qualified Installers and Service Engineers.

Note: Many problems can be attributed to poor pilot flame length caused by blocked jets as the orifice is very small. If the flame length is much shorter than that shown in the Diagram, the pilot may have to be changed. See Diagram 7.

It is always worth using the nozzle of a vacuum cleaner over the end of the pilot to ensure that it has no debris within it. In addition, many ignition problems are caused by incorrect spark
